A CORPORATION OF ,VIRGINIA LOCK Application filed November 26, 1928.Serial R0. 321,946.

object isdefeated by the failure of users to tightly close the lids andlock them in that position which can be done by turning a key to operatethe lock.

It is the primary object of my invention to 1 provide a combined latchand lock for such chests so that the mere act of closing the lid of thechest insures it being automatically latched in the closed position; afurther object of my invention is. to provide means independent of thelock key to readily release the latch; and with these and other objectsin view my invention consists of the parts and combination of partshereinafter pointed out.

In the drawings:

Figure 1 is a detail sectional view of a receptacle with my lockapplied.

Figure 2 is a rear elevation of the lock detached and with the backplate removed.

Figure 3 is a view similar to Figure 2 with the locking bolt removed.

Figure 4 is a sectional view on the line 4-4, Figure 3, looking in thedirection of the arrow, showing the keeper in latched position.

Figure 5 is a view similar to Figure 4 showing the parts in unlatchedposition.

Figure 6 is a rear elevation of the lock detached.

The reference numeral 6 designates a chest or other container having alid or closure 7 provided with a catch 8 of any approved construction.

The lock plate 9 is provided at its top edge with a flange 10 having anopening 11 through which the catch 8 may project, as shown in Figures 5and 6, when the lid is in closed position. The lock casing wall 12 issecured to the plate 9 and is provided with notches 13 in which thetrunnions 14 of the movable latch plate 15 are journalled, whereby theplate 15 may move, rock or swing on said trunnions, so as to move intoand out of engagement with the catch 8 as shown in 50 Figures 4 and 5,Thus keeper or latch plate carries the usual key pin 15*. A push pin 16is also fixed to the keeper or latch plate 15 and positioned,preferably, below the key pin 15, but is longer than the key pin andprojects out beyond the front wall of the chest so that it may bereadily and conveniently operated, the plate 9 of the lock having anelongated opening 17 through which the key pin and push pin 16 project.

A lock bolt 18 is slidably mounted in notchesvformed in the casing wall12 so that it may be moved bodily transversely of the casing Wall 12within certain limits, and is held in assembly position, as is thekeeper plate 15 by means of the back plate 9 of the lock. This bolt isprovided with an arm 20 slidably mounted in anotch in the casing 12, oneend of the bolt being provided with a comparatively wide upwardlyextending flange 21, which when the bolt 18 is moved to the dottedposition (Figure 2) bridges the joint between the rocking plate 15 andthe casing wall 12, thereby locking the rocking plate against movement,whereas in its full line position (Figure 2) .it leaves the plate 15free to rock. Recesses 22, 23, are provided in the under edge of thelocking bolt 18 whereby when'the bolt is moved to the right the recess23 engages a stop 24 and is held in that position by means of the spring25, one end of the spring being secured to the plate 9.

The lower edge of the bolt 18 is provided with a cam like face 26,against which the key, when mounted on the pin 15, is moved to throw thebolt to locked and unlocked position.

A spring 27, one end of which is anchored to the plate 9, bears againstthe keeper plate 15 and holds that plate normally in the position shownin Figure 4, butat the same time permits the plate to rock to theposition shown in Figure 5 to permit the catch to pass downward andengage the opening'28 in the plate 15 as shown in Figure 4.

To latch the lid in closed position it'is only necessary to fully closeit, whereupon the catch will engage and lock with the keeper plate 15.Now, when it is desired to open the lid it is only necessary to pushinward on the pin 16 and thereby rock the plate 15 to the position shownin Figure 5 whereupon the catch 8 is free and the lidmay be opened. Tolook the lid against unauthorized opening the bolt 18 may be moved tolocked position by the key.

What I claim is: 7

In a lock, a casing having a latch opening through its top Wall, akeeper plate pivotally mounted in said casing and having an openingthrough its upper end portion adapted to receive a latch, a key operatedlocking bolt in said casing adapted to be moved relatively to the keeperplate to lock the keeper against movement a key pin on said keeper plateand a push button on said keeper plate.

In testimony whereof I afiix my signature.

JOHN HOGAN.
